IMPROVEMENT IN VEGETABLE GRATERS.

Specification forming part of Letters Patent No. 117,924, dated August 8, 1871.

To all whom t may concern:

Be it known that I, CHARLES R. PEmoE, of the city of Philadelphia, iu the State of Pennsylvania, have invented certain Improvements in Graters, of which the following is a specilication:

My invention relates to the graters used for grating vegetables, crackers, 85e.; and consists of a flat sheet-1n etal plate and a wooden frame or platform, constructed, arranged, and combined together, substantially as hereinafter sh own and described; the object of my invention being to afford a more effective and durable grater, and at a less cost than those of equal size made of sheet metal entirely, as heretofore.

Figure l is a plan view ofthe upper or gratin gside of the said improved grater. Fig. 2 is a vertical longitudinal section of Fig. l. Fig. 3 is a vertical transverse section cut on the dotted line a y of Fig. l.

The grating-plate A consists of a flat sheet of tin-plate about four and three-quarters of an inch by six and three-quarters, more or less, perforated from one side so as to produce a numerous series of quadrangular holes, a a, 1n diagonal lines crossing each other, each hole being about an eighth of an inch square, and forming on the opposite side four curved or angular elevated grattin g or cutting-edges inclined toward each other, as represented in the drawings. The fra-me con sists vof two wooden platforms, B B, each about three by four or five inches square and threeeighths of an inch thick, more or less, connected together by two wooden side pieces, b b', each about twelve inches long, one inch wide, and threeeighths of an inch thick, more or less, which are nailed to the two respective edges ofthe platforms B B so as to leave an open space, b, of

`rectangular form, between themyand so also that the two side pieces b b will form respective side guides or curves about half an inch high, more or less, along the upper side of the frame. These side pieces have each a groove, 3 3, (see Fig. 3,) cut along in their inner sides so as to receive in the said grooves the side edges, respectively, of the plate A, which has its two ends, 2 2, nailed down to the respective platforms B B, as shown in Figs. l and 2.

It will be readily understood, without further description, that the comparatively exten sive and fiat grating-surface formed by the tin-plate A and its application to the wooden platform B B and side 'guides b b', as described, will afford a more effective and durable grater, and at less cost than those made entirely of sheet metal and of the saine size'.

I claim as my invention- As an article of manufacture, the vegetable grater hereinbefore set forth and described.

CHARLES It. PEIRGE.
